　　LBY-3Top plate delamination instrumentClassification:

　　LBY-3Top plate delamination instrumentThere are mainly two types, one is the LBY model which is T-shaped, and the other is the ZKBY tray type.

　　The number of detection points generally includes 1 point, 2 points, 3 points, 4 points, 6 points, 8 points, etc., among which 2 points and 3 points are commonly used. This product has a simple structure, is easy to use, has intuitive readings, and is inexpensive. It is one of the pressure observation products for coal mines. The top plate delamination instrument has low cost and is easy to use and install.

　　Through the observation of roof delamination in various anchor net tunnels, it is widely recognized that roof delamination observation plays a certain guiding and warning role in the support and reform of anchor net tunnels. Based on the data analysis observed by the roof separation instrument, different geological conditions, lithological changes, etc. were obtained. The separation amount within the anchor net range of the anchor net roadway was summarized, and other effective support measures were taken in a timely manner to prevent roof collapse accidents and ensure production.

　　LBY-3Top plate delamination instrumentstructural composition

　　The roof separation indicator mainly consists of a base anchor head, a measuring rope, a sleeve, an inner measuring cylinder, and an outer measuring cylinder.

　　First, install the deep base anchor head, use the installation rod to send the anchor head to the design position, and tighten the measuring rope when sending it in.

　　Insert the shallow anchor head into the installation position.

　　3. Install the sleeve, firmly connect the bottom end of the sleeve to the waterproof plate, with the bottom edge of the waterproof plate about 35mm away from the top plate. Then connect the deep anchor head measuring rope to the inner measuring cylinder, and the shallow anchor head measuring rope to the outer measuring cylinder.

　　Align the zero point of the outer measuring cylinder with the bottom edge of the casing, and align the zero point of the inner measuring cylinder with the bottom edge of the outer measuring cylinder.

　　LBY-3Top plate delamination instrumentObservation of working face:

　　(1) Support condition (backing and thickness, leakage, straightness, spacing between supports)

　　(2) The condition of the roadway roof and the condition of the coal wall lining.

　　(3) Measure the mining height to see if top and bottom coal are left.

　　(4) Whether the front and rear exits are unobstructed.

　　(5) Observe the condition of the hanging plate in the ancient pond, record and collect the readings of the pressure gauge and the integrity of the pressure gauge.
